EDWARD HINES, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR F ONE-HALF TO WILLIAM H. BROOKS, OF ST. DAVIDS, PENNSYLVANIA.

To all whom it may concem: I

.Be it known that I, EDWARD citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new. and usev ful Deinking-Machine for Platen-Wipers,

ofwhich the followingis aspecification.

which is ordinarily paper, and on this paper the ink is collected. Unless means are employed to remove the ink from the paper there is a considerable loss in the consump tion of the amount of ink employed, and

also a. considerable loss of paper.

to devise novelmeans for recovering the ink It is the object of mypresent invention from the paper in such a manner that both the ink and aper can be used over again.

With the a ove in view my invention comprehends a novel construction of a deinking machine for platen wipers.

vention I have shown in the accompanying,

correspondingparts in the figures Referf Otherv novel features of constructlon. and

advantage will hereinafter appear in the detailed description of my invention.

. For the purpose of illustrating my indrawing atypical embodiment of it which in practice will give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which-my invention consists can be vari ously arranged and organized, and that my.

invention is not limited to the exact arrange .ment and organization of these instrumentalities as herein set forth.

the bracket 6 secured in any desired manner to the side members 2. The slot 5 opens tion. The platen 3 thenjpasses beneath a .roll 8 journaled in arms 9 integral with'or .In power operated stamping presses of the plate and die type as ordinarily used a wiper is employed in the form of a platen against the lower ends of said scrapers. The

platen; 3 then passes over a composition roll 13 mounted on a shaft 14 which is jourinaled in slots 15 in theside members 2.

This roll extends into a pan 16 which is substantially trough shape, and provided at its ends with flanges '17 which rest on the side members 2. The roll 13 is in contact with the solvent 18 such as for example turpentinefand coal oil, it being understood that any desired or suitable material may be employed for thispurpose.

The pan 16 forms a solvent container and is provided with a discharge spout 19. The platen passes over the roll 13, and then downwardly beneath a roll 20, the ends of which are journaled in the side members 2 in any deslred manner. The platen then passes upwardly over a scraper 21 the ends of which are mounted in the inclined slots 22 in the sidemembers 2. Set screws 23 are provided in threaded engagement with the side members 2 and adapted to contact with the scraper 21 in order to effect its vertical adjustment.

Set screws 2a are also provided which are in threaded engagement with the side members 2 and bear againstthe scraper 21 in p t t t a order to lockit in its adjusted position. The deinking machme is secured with re- The platen 3 then passes over a cleaning roll 25 the surface of which is covered with absorbent material 26 and the ends of this roll are journaled in slots 27 in the side members 2. The platen 3 then passes beneath a roll 28 journaled in the side members 2 and therefrom to a desired point of utilization. i l I I The base 1 is provided with a pan 29 withwhich placed the pans 30 5111 131: he

the scraper 10'the greater partof this ink pan 30 serving to collect the ink removed by the scraper -10,and the pan :3l serving to collect the oil and ink removed by the scraper 21, and the cleaning roll 25.

In order to maintain the supplylofsolvent in the solvent container 16, I provide a pipe 32 leading from a source of solvent supply (not shown), and discharging into the solvent container 16.

,The operation will now be readily understood by those skilled in this art and is as follows? i g I The platen 3 which serves as, a Wiperhas one side thereof coated with ink asit comes out of'the stamping press. In passing over [carried by thepla'ten is removed and falls 7 into the collecting pan 30.1 The platen then passes over the ,roller 13 which causes the ink solvent. to come; into contact with v the "paper, so that when the platen passes over the second scraper 21 thesolvent and ink wi11'be scraped therefrom and dropped into ,jthe collecting pan 31. 'l he platen then passes over the roller 25 which acts as a cleaning roller to remove the oil and ink from the platen.

The platen is now in such conditioirso that ,it can beused over again'as'a' wiper,

condition that it can a-lsobe usedagaind and the ink in the pans 30 and 3lfis in'such 'In many cases arising in practice 'the 1 rollers l: and, 8 can be dispensed with if desired.

The rolls 13, 25 and 28ia re preferably journaled in the same horizontal planefand ters Patent, is

the rolls 20 and 28 havepreferablya smaller diameter than the rolls 13and E25, whilethe roll 25 is the roll 13.
